Ingredients

graham cracker crust;

  • cups graham crackers (roughly 1½ sleeves)
  • ½ cup sweetened flaked coconut (optional)
  • cup butter, melted
  • 2 Tbsp brown sugar

key lime filling;

  • 20 oz sweetened condensed milk (scant 2 14oz cans)
  • ½ cup sour cream (or sub high fat greek yogurt)
  • ¾ cup key lime juice (e.g. Nelly & Joe's)
  • 1 Tbsp lime zest

Instructions

graham cracker crust;

  • Manually crush, or use a food processor to crush graham crackers into fine crumbs. Add the graham cracker crumbs to a medium bowl.
  • Add ½ cup sweetened flaked coconut and 2 Tbsp brown sugar. Toss together until mixed.
  • Melt the ⅓ cup butter in the microwave, and then pour over the dry crust ingredients. Stir together until evenly coated.
  • Pour into the bottom of a 9"x13" pan and press evenly across the bottom. I prefer to use the flat surface of a measuring cup or the like. Bake at 350° for 8 minutes.

key lime filling;

  • In a medium bowl, add 20oz of sweetened condensed milk, ½ cup sour cream, ¾ cup lime juice, and 1 Tbsp lime zest. Mix well until smooth. It may take a minute or two for all the ingredients would combine smoothly, just keep stirring.
  • Pour mixture on top of crust and smooth across the pan. Optionally add an extra little grate of lime zest for extra color.
  • Bake in oven 5-8 mins until tiny pinhole bubbles burst on thesurface of the pie. Chill thoroughly before serving. Garnish with whipped cream, toasted coconut, and/or berries as desired.
